Complete environmental monitoring with luminosity, eCO₂, indoor air quality (IAQ) and atmospheric pressure, for environments where air quality is as critical as temperature.
Complete environmental monitoring with luminosity, eCO₂, indoor air quality (IAQ) and atmospheric pressure, for environments where air quality is as critical as temperature.
Air quality, temperature and humidity at a single monitoring point, with traceable records to support occupational health, safety and GMP programs.
Continuously tracks eCO₂ and the IAQ index, highlighting air quality variations and peaks, plus luminosity and atmospheric pressure, to flag deviations and trigger alerts at the right moment.
Generates documented evidence for occupational health & safety and air-quality programs, supporting requirements for chemical agents and environmental comfort in the workplace.
Temperature, humidity, luminosity, eCO₂, IAQ and atmospheric pressure in a single compact device, a single installation and maintenance point. After an initial commissioning of about 30–60 minutes, the calibration stays saved on the device, restarts don't require recalibration.
The platform calculates the IAQ Score, the indoor air quality index, combining all the A500 readings into a single index that makes trends and deviations easy to read, with automatic alerts at deterioration peaks.

Let the A500 run for 30 to 60 minutes in its final environment before considering the IAQ calibrated to maximum accuracy. That's the time the sensor needs to adjust to the actual conditions of the location.
Once commissioning is complete, the calibration state stays saved on the device itself. Power outages and restarts don't require recalibration: the A500 immediately resumes calibrated operation.
The IAQ is an index focused on trends, comparisons and air quality peaks. Use it to track how the environment varies over time and to trigger alerts, rather than as an absolute laboratory reading.
The A500 connects to the PLEXOR IoT platform and automatically generates the IAQ Score, configurable alerts per variable and reports ready for occupational health & safety and audits.
Generates continuous environmental records for occupational health & safety programs, with air quality indicators (eCO₂/IAQ), temperature and humidity traceable per device.
Tracks temperature, humidity and air quality indicators in pharmaceutical production areas, supporting the environmental monitoring of Good Manufacturing Practice (GMP).
Tracks temperature, humidity and air quality indicators in enclosed environments with electrical equipment, helping to anticipate ventilation problems.
eCO₂ variations in storage environments can indicate fermentation or spoilage, helping to identify early signs before the problem advances.
Elevated eCO₂ levels signal insufficient ventilation. The A500 monitors and alerts automatically, supporting ventilation and comfort decisions.
Tracks temperature, humidity, pressure and air quality indicators in storage environments for fruits and vegetables, supporting the preservation of shelf life.
You buy the hardware
